To all whom it may concern: y

Be it known that I, FRANK S. HEBDEN, a citizen of the United States,residin at Peoria, in the county of Peoria and tate of Illinois, haveinvented certain new and useful Improvements in Scales, of which thefollowing is a specification.

My invention relates to scales and has for its object the weighing ofgrain or other material as it flows in a constant stream or while it isconveyed through a chute or trough. v

My invention relates principally to means for conducting grain or othermaterial from discharge to receiving members disposed in a relationrelatively to cause the grain to readily flow from one to the other; tomeans actuated by the flowing grain to transmit power to actuate -atally mechanism; to

means for suspending the grain conveying structure or hopper upon anormal balance; to means as a weight or spring, serving to resist thedepression of the conveyer or hopper under the influence of'the weightof grain flowing therethrough; to means associated with the hopper andthe tally mechanism actuated by the force of moving grain in the hopperto operate the tally mechanism and associated in a relation to vary thespeed of cooperating parts for the purpose of properly weighing thegrain as it flows through the hopper in variable quantities.

My invention further relates to combinations of parts and details ofconstruction hereinafter more particularly described.v

In the drawings, Figure 1 is a front elevation of my device with aportion of the scale beam adapted to carry a weight removed; Fig. 2 is atop view of my device; Fig. 3 is a side elevation of the same, viewedfrom the direction as indicated by the arrow in Fig. 1, having a portionbroken away to show interior construction; Fig. 4 is a side elevationviewed from the opposite side of the structure from that disclosed inFig. 3,

. with portions broken away to better disclose interior construction;Fig. 5 is a vertical sectional view, substantially upon the line a.a ofFig. 4, showing parts broken away to illustrate certain detailconnection of parts; and Fig. 6 is a detail view.

In the drawings, as disclosed in Figs. 2, 3 and 4, 2 is a housing orframe structure, which will hereafter be referred to as the hopper,provided with an inlet opening in the wall thereof, with which is conneted the tom of the hopper 2 adapted to deliver into a hopper 5 which issuitably supported at the mouth of the opening and from which I grainmay be delivered to any point desired.

The hopper is connected with a scale beam 6 by means of the yoke 7 whichengages trunnions upon the scale beam. The scale beam is furcated ordivided in the manner shown in .Fig. 2 and is supported upon a suitableknife edge upon the arm 8 secured to a suitable frame-structure whichsaid arm may be reinforced by means of a brace as 9. 10 is a balanceweight supported upon the screw thread extension from the scale beam, asparticularly shown in Fig. 2. The weight of the hopper and itsassociated mechanical parts is adapted to be counterbalanced by theweight 10 on the scale beam so that when free from a load of grain andfree from the supplementary spring pressure adapted to be applied inconnection with the operative structure, the hopper will be balanced inthe position shown in Fig. 5. A paddle wheel is designed to besupport-ed within the hopper adapted to be turned by the contact ofmoving grain passing through the hopper. This paddle wheel comprisespaddles as 11 connected with a sleeve 12 by means of ribs thereonsubstantially in the manner shown in Fig. 5 and said sleeve is adaptedto be secured to shaft 13 journaled in boxings 14 in the walls of thehopper. The particular means of connecting the sleeve with the shaft/isshown in Fig. 5, in which a stud on the sleeve is shown seated in adepression in the shaft. 15 is a disk wheel secured to said shaft 13 bymeans of key 16. 17 is a framework supported by means of rods 18, oneconnected with scale beam 6 and the other with the frame 17, the tworods being connected by means of turn buckle 19. The frame 17 isprovided with the upwardly and downwardly projected arms 20 and 21supported in a relation that with the movement of the connected partsits position will be changed.

is a disk wheel supported upon shaft 26 in a manner to cause it to havea constant bearing relation against the outer face of disk 15. The shaft26 is journaled in a framework 27 which is pivoted as at 28 to a stud orarm on frame 17.

29 is a pin projecting laterally from frame piece 17 adapted to bearthrough a perforation in framewrok 27 and 30 is a coil spring interposedbetween frame parts 17 and 27 to provide a resilient force to be exertedagainst frame 27 to cause disk 25 to bear constantly against the surfaceof disk 15. The upper end of shaft 26 is carried through a journalhearing at 31 in frame 17, said journal being of sufiicient size toallow a slight lateral movement of said shaft to and from disk 15 tocompensate for any variation of the surface of disk 15 from a verticalplane in line with the face thereof.

32 is a register, but as this register does not constitute any part ofmy invention, the particular construction of the same is not shown andis not described. The register is supported upon an arm 34 secured toframe 17 and in addition to supporting the register, it supports ashaft, miter gear and a cog wheel, the miter gear adapted to mesh with amiter gear upon the upper end of shaft 26 and the cog wheel adapted tocoiiperate with suitable cog connection in the meter to properly actuatethe latter to effect the proper operation of the register.

35 is a spring connected at one end with the scale beam, and the otherend thereof being threaded and provided with a thumb nut is connectedwith the arm 36 which has a fixed connection with a stationary frame 37.Spring 35 is adapted to exert a counteracting force against the weightof grain as in the operation of the machine such grain is passed throughthe hopper in a continuous stream and it is the regulated tension of thespring that is intended to serve as the proper expansible force thatwill permit disks 15 and 25 to be adjusted relatively through themovement of balance bar 6 under the influence of the hopper as it isdepressed in difierent degrees under any variations in the weight of thematerial flowing therethrough.

In applying the structural parts, the weight of the hopper is firstbalanced by means of weight 10 so that it will occupy the position shownin Fig. 5, then the spring 35 is attached and properly adjusted by meansof the thumb nut to exert a force to position the parts as shown in 1 sothat disk 25 will bear exactly at the vertical and horizontal center ofdisk 15.

38 is an adjustable rod provided with stop nuts 39 to limit the upwardand downward movement of the scale beam.

40 is a housing adapted to inclose frame 17 and its connected parts andparts connected with the hopper that are designed to cotiperatetherewith and is provided for the purpose of protecting against dirt andrefuse that might accumulate thereon and interfere with the operation ofthe device.

In the operation of the device, in weighing grain or other material,such material is adapted to be delivered into chute 3 from which it willbe deflected into hopper 2, the grain so entering passing along thetrough portion 4 of the hopper and finally out through the opening inthe bottom thereof and into hopper 5. The grain will exert a varyingforce, according to quantity, in weight to depress the hopper and inpassing will contact with the paddles l1, causing the wheel to be turnedat the same speed as that of the moving grain and with it shaft 13 anddisk wheel 15; The variable Weight of the grain passing through thehopper will effect a variable vertical movement thereof, controlled andregulated by spring 35, which spring is itself regulated to exertaresisting force properly proportioned, as common in the ordinary springscale. The downward movement of the hopper effecting a downward movementof the end of the scale beam with which it connects, will cause anupward movement of the opposite end of the scale beam at points beyondits fulcrum support, and because of the connection of frame 17 therewiththrough rod 18, the framework 17 will be raised, carrying with it thedisk 15. In proportion as the weight is added to that of the hopper bygrain being introduced therein, resulting, in the hopper beingdepressed, disk 25 will be moved from its normal position, which is atthe center of disk 15, upwardly with relation to said center point, thatis, disk 15 will move downwardly and disk 25 upwardly, owing to thereverse direction of movement of their respective supports, andproportionately the same distances, and as the weight of the grainvaries, resulting in different degrees of depression of the hopper, sothe distance between the center point of disk 15 and that of disk wheel25 will be changed. It is the communicated movement of disk wheel 25from the center of diskwheel 15 that causes the register to be causesdisk 25 to be turned, and the rapidity of the turning of disk 25 willdepend upon the distance of the bearing contact from the center of disk15the greater the distance from the center, the faster disk 25 will beturned. Any variation in the speed of the grain as it travels throughthe hopper, in creasing the speed of the movement of paddle, will effecta corresponding acceleration in the speed of disk 25. I

It will be seen from the above description that a cooperating connectionbetween the hopper upon one sideof the fulcrum point of the scale beamand the part connected with the other end of the scale beam is madeshiftable relatively to accomplish the measuring by changing the speedof a driven part connected to operate the register, effected by the riseand fall of the hopper.

In practice, the parts being in normal adjustment as in Fig. 1, thepaddle wheel can be turned by hand without effecting the turning of disk25, as the contact is directly at the center of disk 15, but as weightis added by infiowing grain, disk 25 moves from the center point and asits distance from the center point is increased by increase in theweight of grain in the hopper, it will move farther and farther awayfrom the center point, and as it moves farther away, will have aconstantly longer surface to travel with the same revolution so that asdisk 25 moves from the center point toward the circumference of disk 15its speed will increase, resulting in a corresponding increase in speedof mechanism connected to operate the register, and thereby measuringthe grain in proportion as its added volume increases the weight as itpasses through the hopper.

Obviously, a basis of measurement must be established by causing theregister to record the length of movement of disk 25- by firstestablishing a unit of measurement, which multiplied will effect theyresult, the same as in the ordinary gas meters and the like. As thisprinciple of establishing unit of measurement is-common, it is deemedunnecessary to particularize upon this point.

The structural combination herein disclosed is intended to representonly one form of embodiment of my invention. But form is not the essenceof the invent-ion. Obviously, it may be embodied in many forms ofconstruction that will serve as well to carry out the principle andtherefore do not wish to confine myself to the construction herein shownand described as it is merely ofiered as a means to illustrate theprinciple.

Spring 35 is merely shown as a type of counter force adapted to serve asa measured resisting force against the depression of a hopper.

I have shown rods 18 connected by turn buckle 19. This. mechanism isprovided. to

compensate for any lost force resulting from use in any resilientconnection, as 35, thatmay be used between scale beam 6 and the fixedarm36.

My invention is adapted for use in measuring any commodity or materialthat may be caused to flow through an inclined trough or hopper, as forinstance, water, coal, or other substance, and grain is referred toherein as representing one of the commodities'it is capable of weighing.
